تأثير الماء الممغنط في مقاومة تآكل الصلب الكاربوني و حديد الصب

الملخص EN

In this research, corrosion tests carried out for the most important types of carbon steel and cast iron used in different applications.

The research included experimental work by using drinking magnetized water in comparison with non-magnetized water under the same conditions.

The water was passed through a continuous magnetic field with a flux density of (1685) Gauss, and corrosion rates were measured according to the standard (ASTM-G31-O4).

The results indicated that water properties were effected by using a magnetic field so that the corrosion rates of steel and cast iron in magnetized water are slightly higher than in normal water, while the scale formation on surface of the samples corrosion in magnetized water were appeared less than in normal water .

These results also showed the relationship between the corrosion resistance of steel and cast iron with microstructure, so that at the beginning of the test the types of cast iron had a high corrosion rate, but gradually these rate started to decrease till it approximately approached the corrosion rate of types steel whether magnetized water or normal water was used .
